Lots of headroom for overclock. If your considering just do it. currently banging a +156mhz overclock with a bit more head room. Playing mad max at 5760×1080, ultra (three screens) 50 – 60 fps. Crysis 3 the about 45 frames at mostly max, same resolution. And yes, it'll play Minecraft..
But
GET THE G1 edition for the back plate and higher base clock (clock wont matter as much if your going for an overclock)
